The performance failure and reliability of motion mechanism has a significant effect on industry reliability, operation safety production economy. Motion precise is one the typical indicators especially for with multibody joints. Size joint clearance degenerates usage such as wear deformation. Repeated start-stop lead to impact stress plastic deformation particularly high load long working cycl...

This paper establishes a dynamics model for deploying solar panels with clearances by using a practical method and provides a useful way to identify the effects of clearances on spacecraft systems. Considering the clearance of joints, a contact dynamic model is established using the nonlinear spring-damp model and the friction effect is considered by using the Coulomb friction model. Based on t...

Mebendazole was given to two patients with multiple hydatidosis of the liver and three patients with multiple hydatidosis of the lungs. They could not be treated surgically because of aduanced diseases. So they wer given a daily dose of 25-40 mg/kg body weight for 9-12 months. Definite clinical result in one patient and some clinical improvements in the size of the liver and clearance of the lu...

The introduction of carbon-fibre reinforced plastics in load bearing automotive structures provides a great potential to reduce vehicle weight and fuel consumption. To enable the manufacture and assembly of composite structural parts, reliable and cost-effective joining technologies must be developed. This thesis addresses several aspects of joining and load introduction in carbon-fibre reinfor...

Clearances caused by assemblage, manufacturing errors and wear, affect inevitably the dynamic responses of mechanisms such as robot manipulator. In this study, effects clearance on a manipulator system are investigated numerically. The contact behavior along normal tangential direction joint is described nonlinear force model modified Coulomb friction respectively. Then, dynamics equations esta...

Arthrogryposis as a congenital malformation that refers to the fixed flexion of one or more joints as a result of stiffness or limited movements of multiple joints, change of posture and limb function due to permanent contracture of joints and wasting of muscles that usually occur at early stage of gestation. This report describes congenital arthrogryposis associated with musculoskeletal defect...

tracheomegaly or tracheobronchomegaly is a rare syndrome which is characterized by dramatic dilatation of the trachea and the major bronchi. this syndorme is usually associated with chronic respiratory infection and airway obstruction. in this paper, a case with tracheomegaly and bronchiectasis was scrutinized.

OBJECTIVE To investigate whether identical T cell clonotypes accumulate in multiple rheumatoid joints, the clonality of T cells that had infiltrated into synovial tissue (ST) samples simultaneously obtained from multiple joints of patients with rheumatoid arthritis (RA) was analysed. METHODS T cell receptor (TCR) beta gene transcripts, amplified by reverse transcription-polymerase chain react...
